A/CTA-50

The A/CTA Series current sensors monitor the current flowing to electrical equipment or buildings. The magnitude of this current is then converted into a linear and proportional 4 to 20 mA output signal, which can be monitored by your Building Management, DDC, or PLC controller. The A/CTA Series current sensors are available in either an Average or True RMS output version. All of these sensors have jumper selectable input ranges except for the 0 to 5 Amp input range on the A/CTA-05 series sensors.

The A/CTA series current sensors are fast acting and extremely accurate from 1 to 100% of the Full Scale Output. All of the A/CTA series current sensors are factory calibrated using a NIST Traceable standard and shipped with the jumper placed in the largest jumper selectable range. They must be externally powered using a +12 to 30 VDC power supply.
